I would like to know:
1. What is stock SoC
2. What is safe NB SoC for normal daily use (sometimes big CPU load - blender render).
3. Is it better to set SoC constant or offset?
4. Is problem described below looks like a bios or CPU problem?
Recently I did an PC upgrade
i5 2500k -> Ryzen 5900x
Asrock P67 Pro3 - MSI Tomahawk X570 WiFi
Memory
GPU is waiting for the new year (GTX780 currently)
For now, I'm not interested in OC. Such CPU change is boosting my system enough.
But I have a big problem. My purchase was 14 days ago and till now I don't have stable system.
PC reboots randomly.
PBO - off
Checked 3 PSUs
memtest 24 hours passed
I did tests with XMP on and off
Started to think about changing mobo, but it seems that this problem happens on MSI. Asus and Gigabyte (mayby more)
Temperatures at max usually 72 degrees. Sometimes little more at peak.
In blender benchmark in 6th test called Victor.
I tried to run Witcher 3. 4 attempts - 4 reboots
low/moderate load - images conversion (cores used at 10-15%)
Only one solution was to disable Core Performance Boost but with CPB disabled 5900x looses to much performance being locked at 3700MHz
I'm not alone with this problem. There is a topic on AMD community forum.
One guy said that MSI support email him with advice to change NB/SoC voltage from auto to + little offset.
I tried this. It helped with blender benchmark - 2 passed tests in a row. First time.
But it didn't help with normal usage - still random reboots. In blende is much better but still not 100% stable.
My bios at SoC auto shows 1.115V, but I'm not sure how precise it is. On full stock vcore in bios shows 1.4V and in the system 1V so quite a difference
SoC at 1.05V didn't give me stable system. Another crash in blender. I just don't know how high could I go.
